SMC-M 20mm f4 - scratched front element
The scratches are widespread, but very light. I will try it with a hood, but I doubt the original Asahi Pentax skylight filter it came with will help very much. A pity the owner didn't make more use of the filter! The lens has clearly had a lot of use :wink: Looking through my shots, blues seem e...

Pentax 18-135 not recognized
My Pentax 18-135 is not recognized by my camera and shows up in EXIF data as "unknown lens", and that happens also with the latest firmware update. I had read that others had the same problem, is that the case? I would assume that if it is not recognized, then also in-camera lens correction would no...

SuperTakumar105 vs SMC105... which one goes ?
Thanks :) +1 for selling the Super Takumar (much as I'd like to buy a K105!), assuming that both are in good shape. yes the plot thickens a little here...The Tak has a few stains that may actually be on the outside of both ends, will have a wee clean and see. The K lens has sadly been 'fixed' by ...

SuperTakumar105 vs SMC105... which one goes ?
it's just that they seem to have used pliers to do it Ah yes, I've got a K50/1.4 like that. Works very well, though. I've fitted a filter with the glass removed to allow the lens cap to fit/make it look a bit tidier. It's a shame that people are so ham-fisted at doing repairs like that, especial...

SuperTakumar105 vs SMC105... which one goes ?
Yep tragic how they do that ... I dented my K50/1.2 but had the experts ping it out and glad I did. I did the empty filter ring trick when I got it back. Had tried a shaped wooden drift and also a press with inside and outside shaped jaws. Practice runs on a junk lens were revealing. I think you ...

SuperTakumar105 vs SMC105... which one goes ?
I was very lucky with a K 28-50mm in that the filter had taken all the damage a previous owner inflicted. Now if only it had been able to keep the fungus out too...

older Prime vs newer Zoom
[quote:3496ace15f="Pwynnej"]I think this is a rather futile discussion... I think I should look for an excuse to take out the FA*85 to see how it compares with the DA*60-250 when it's returned from Pentax. It might be futile if you have a shelf of * lenses. think you misinterpreted my messa...

older Prime vs newer Zoom
I've tried 3 FA*24/2's and non could match the Sigma edge sharpness until f/8, but had much higher contrast. Sample variations aside, this also depends on the design parameters of a lens. Most 24mm lenses would actually normally be used at small apertures, so it could be that it was designed to peak...

cosina 100 macro AF
Reasonable lens I think, just a bit plasticky. I took this with it - not the best shot I ever took, it was dark and I was wallowing on the floor trying to get a sharp shot with slow shutter speeds / wide apertures: The shot is cropped quite a bit, maybe 50%. It's not a full 1:1 macro, onl...

I'm sure they came with the close-up filter?

cosina 100 macro AF
Algi is correct. The lens is 1:2 macro and should come with a filter to make it 1:1 magnification. It was made under numerous brand names including Cosina, Phoenix, Vivitar and a few others. They did both manual and autofocus versions. Not a bad little lens actually, build quality is a bit iff...

Replacement hood for Limiteds
Matt, i tried DA*50-135 and it shows same amount of vignetting as DA70. On contrary FA31 shows not visible vignetting on MX at all. If I remember well, MX viewfinder covers 95% of image. I guess you can use DA70 on fullframe and you wouldn't see any boundary made buy edge of filter thread, but you w...

WTB: decent 52mm close up filter / macro filter / 1:1
Looking for a decent 52mm close up filter. Achromatic or the like, multicoated etc.. Not just a bog standard one. Maybe a Sigma Life Size filter or a macro adapter or 1:1 adapter. Preferably +3 or +4. Thanks
